BATTERY-LIGHT ATTACHMENT.

T 0 all whom it may concern:

Be it known that I, ARTHUR D. SAnonsKY, a citizen of the United States, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in and relating to Battery-Light Attachments, of which the following is a specification.

This invention relates to improvements in battery lamp attachments, more particularly to a device for holding a miniature electric bulb upon any well known type of dry cell which has a pair of outwardly extending electrodes at one end thereof.

An object ofmy invention is to provide a simple, inexpensive, effective and durable attachment which may be quickly and easily attached to and detached from the dry cell, and may be employed either for flash lighting or continuous lighting purposes as desired. I

Other objects of my invention will be obvious from the description of devices embodying it which I have herein selected for the purpose of illustration.

Figure 1 shows an attachment embodying my invention partly in side elevation and partly in section.

Fig. 2 is a top plan view of the same.

Fig. 3 illustrates in full. lines the attachment connected to one standard form and in dotted lines to another standard form of dry cell.

Fig. 4 is a perspective view of a dry cell with one of my attachments fitted thereto.

Figs. 5 and 6 show modifications.

In the drawings, 1 is a combined reflector support and electrical conductor. It preferably consists of a strip of resilient sheet metal having a section 1 perforated at 1", a curved offset section 1 extending from the section 1 and bent back upon itself as indicated at 1 to form a resilient base each portion of which is longitudinally perforated as indicated at 1 2 is a reflector of suitable shape preferably provided with a cylindrical, tubular base 2* which is projected through the opening 1 of the combined reflector support and conductor 1, and has its free end upseti against the under side of the element 1 so as to hold the reflector in proper position thereon.

3 is an electric bulb, of standard construction, having a suitable filament with Specification of Letters Patent.

one end electrically connected to the shell 3 of the plug 3' and its other end electrically connected to the central electrode 3". The plug 3 is inserted through the tubular base of the reflector and is held in proper position by a suitable nipple 4.

5 is a dry cell of standard construction having the electrodes 6 and 7. The cell is preferably of curvilinear shape-in cross sectlon. In order to fit one of my attachments to the dry cell all that is necessary is to see that the thumb screw 6 for the electrode 6 is removed, whereupon this electrode is projected through the slots 1 of the combined reflector support and conductor 1. The thumb nut 6 is then screwed back upon the electrode so as to engage the base section 1 of the element 1. If it is desired to use the device for the purpose of flashing light, the thumb nut 6 is set up so that the central electrode 3 at the lower end of the plug 3' is adjacent to but does not engage with the electrode 7 of the dry cell, as shown. in Fig. 3. The operator then presses downwardly upon either the reflector or its support in order to engage the bulb electrode 3* with the lamp electrode 7, whereupon an electrical circuit is established between the electrodes 6 and 7 through the instrumentality of the element 1, bulb electrode 3 the filament within the bulb and the bulb electrode 3 The instant that pressure on the device is relieved by the operator, the bulb will spring away from the electrode 7 under the influence of the spring action of the metal of which the element 1 is made.

The elongated slots 1. in the foot portion 1 are provided to enable the device to be readily adjusted to dry cells in which the distance between the electrodes 6 and 7 may vary, but more particularly in connection with the curved ofi'set portion 1, to accommodate for different heights between the top of the electrode 7 and the top of the dry cell with which the lower wall of the foot 1 engages, as illustrated in Fig. 3, where two different constructions of standard dry cells are shown.

In Fig. 2 I have shown the upper surface of the foot or base section 1 at either side of the slot therethrough, indented at 1 so that the lower surface of the electrode thumb nut 6, when engaging with the rough surface caused by these indentations will serve to hold the device properly in place upon the dry cell.

To those skilled in the art of making devices of the class described, many alterations in construction and widely differing embodiments and applications of my invention .will suggest themselves, without departing from the spirit and scope thereof. My disclosures and the descriptions herein are purely illustrative and are not intended to be in any sense limiting.

or example, in Fig. 8, I have illustrated a modification in which the reflector is formed in the metal which constitutes the element 1. Where a relatively small reflector will suflice this device will be found to be somewhat cheaper than the one illustrated in Figs. 1 and 2.

It will be noted that if the proper relationship is established to hold the electrode 3 in contact with the battery electrode 7,

- that the circuit may be disconnected or reestablished simply by swinging the holder about the axis of the electrode 6 so as to force the electrode 3 out of and into engagement, respectively, with the electrode 7.

In Figs. 5 and 6 I have illustrated an attachment in which the contact between the central electrode 3 of the bulb and the battery electrode 7 is established merely by swinging the bulb about the axis of the electrode 6. In this modified construction instead of bending the metal back upon itself, forming a resilient foot which engages with the top of the dry cell at the electrode 6, I have extended the metal outward beyond the electrode 6 and then downwardly as indicated at 1 to form a handle. The handle 1 may also serve as a rest for the cell, thus permitting the latter to be placed on its side on the floor or other suitable support to throw the light in various directions. In this construction furthermore I have bent the reflector end of the support and conductor angularly so as to reflect the light more or less laterally relative to the dry cell.

It will be noted that in view of the fact that electrical contact is made and broken directly between the central electrode of the bulb and the battery electrode with which it alines, that it is not necessary to provide any additional insulation either for the battery electrode or bulb electrode, in other words my attachment does not require the use of any insulating material other than that between the electrodes of the bulb itself.
